CONTINUOUS BRICK DRYING AND BURNING MACHINE. V

SPECIFICATION forming part of Letters Patent No. 496,840, dated May 9,1893.

Application filed February 24, 1892. Serial No. 422,711. (No model.)

To all whom it may concern.-

Be it known that I, SQUIRE AINSWORTH, of the city of Pittsburg, countyof Allegheny, and State of Pennsylvania, have invented a new and usefulmachine for drying and burning bricks, tile, and other articlesmanufactured froirclay in one continuous motion withoutany handling fromthe time they leave the mold and are placed on the machine until theyare dried, burned, and cooled ready for use, of which the following is aspecification.

My invention consists of a long horizontal endless movable table orbelt, with fire clay slats or other suitable material and a furnaceconsisting of a front and grate bars with fire clay sides and ash pan,if desired, suspended across from one wall or side to the other in sucha manner as to permit the said table to pass over the said furnace andthe empty table to pass under the said furnace to the front, and beingso constructed, as to prevent the fuel from falling on the said tablewhile passing under the furnace. The green bricks are placedlon thefront of the table in single rows or layers and as one layer moves tothe furnace another layer is placed on thetable, and

so continued, keeping the table full. The heat coming to the front driesthe bricks slowly at first, the heat increasing as they move to thefurnace, and as they pass over they are burned, and they pass dowmaslide, into the cooling shed. When they are cooled they are ready foruse. When gas or oil can be obtained, it is preferable to other vfuel.The gas or oil pipes can branch from the out side and pass between theupper and lower table, and in case of oil the dripping pan can besuspended across the same as the furnace in such a manner as to permitthe lower part of the table passing under, while the upper table passesthrough the fire with the bricks on the same as the aforesaid furnace.The

pipes can be placed in the furnace and can also extend along the fulllength of the table if desired, with small burners at the front andlarge burners at or in thefurnace for burning the bricks as they passover.

One or more flues may be used to conduct the waste heat from the coolingshed and pass over or at the sides of the table to conduct the wasteheat to the front. A fan or blower may be used to forcea draft if it isrequired.

on rails and removed at the lower end and sent back, but the slats areliable to get broken, and it would entail extra expense in labor, andunnecessary delay in waiting for them to cool off. I am aware of othermeth ods .of the manufacture of bricks, &c.; but they are either tooexpensive in construction or operation or are entirely impracticable inother respects. The most practical manufacturers of bricks that I knowof pile them on cars from six to ten layers high and run them into asteam drying house. After they are dry they pile them in a kiln fromthirty to fifty layers high and burn them. Then they stay there untilthey are cooled off, which is expensivein time and destruction of bricksin handling and burning, all of which I save with my simple process,which is its greatest advocate.

The machine can be made stationary or portable, and can be made insections. The table can be made in sections or links, with wheelsattached to the table, or they may be set in the frame. The sections canbe made in such a manner that a party having ashort machine can order anextra length, or a party having a long machine can remove a length asdesired; also the machine may be set on a very slight incline to enablethe table when loaded with bricks to move more easily.

In the accompanying drawings, Figure 1 is a perspective view of themachine and cooling shed. Fig. 2 is a view of the furnace and a portionof the table or belt formed of double slat lengths. Fig. -3 is a view ofthe oil and gas pipes that maybe used. Fig. 4 is a side View of severalslats of which the table or belt is made.

In the Figs. 1 and 2, A A A A are the four large wheels for moving thetable on. B shows the lower rail in returning under'the furnace E showsthe oil pipes with the to the front. dripping pan. F is the gas pipe. Gis the fuel furnace with ash pan, suspended so as to permit the table topass under to the front. H is the waste heat flue to conduct the air tothe front of the furnace. I is the slide for the bricks to pass into thecooling shed, or I may use another endless table to take them a longdistance and load them on cars or boats. b is the damper. K is the smokestack. L are the rails "for the table to run on. M is the outside frame.N is the cooling shed. O is 25 the fan or blower to force the waste heatto the front and create a draft when desired.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The suspended furnace, for gas oil or other fuel in combination withthe horizontal endless movable fire proof table or belt. as herein setforth.

2. The combination in a continuous brick drier and burner of thesuspended furnace. table or belt. and back damper with a cooling shedand waste heat flue:

3. The aforesaid furnace and table and fan. wasteheat flue cooling shed,back damper, and portable frame, with movable sections, and movablelinks combined,. ih and for the purpose herein set forth.
